SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1213 AM CDT Fri Oct 30 2020 Valid 301200Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Only a few weak thunderstorms are possible over southern Florida today. ...South Florida... Strong short-wave trough, currently located over the southern Appalachians, will eject off the Atlantic Coast early in the day1 period. As this feature shifts east, trailing cold front will settle into south FL then slow as it moves across the FL Straits. This boundary will serve as the focus for potential convective development through the period, especially during the afternoon when boundary-layer heating will maximize buoyancy within a high-PW air mass (1.5-2"). Forecast soundings exhibit substantial SBCAPE ahead of the front with 2000-3000 J/kg expected within a weakly sheared environment. For these reasons, isolated-scattered thunderstorms should be noted across the south FL warm sector later today. ..Darrow/Jirak.. 10/30/2020
